IMPROVEMENT IN CULINARY APPARATUS.

TO ALL WHOM IT MAY CONCERN:

'Be it known that I, JOSEPE S. FIELD, of Brooklyn, Kings county, NewYork, have invented a new and improved Cooking-Apparatus; and I dohereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, reference being had to the accompanying drawings,forming part of this specification, in which- Figure 1 represents alongitudinal vertical section of my improved cooking-apparatus.

Figure 2 is a vertical transverse section of the same, taken on theplane of the line a fig. 1.

Figure 3 is a horizontal sectional view of the same, taken on the planeof the line 3 y, fig. 1.

Similar letters of reference indicate corresponding parts.

This invention relates to a new device for boiling, by steam, variousarticles in one single vessel,which is l divided into variouscompartments by fixed partitions, so that the articles to be boiled maybe separated from each other, that they might retain their originalflavor.

This invention is intended as an improvement on and completion of thedevices which are now used for the same purpose, and which consist oftwo or more vessels put one upon the other. The steam from a boilerbelow, entering all the vessels, boils their contents, but, as theproductsof condensation are carried back to the boiler, andthenevaporated again, the flavors of the various articles become mixed, andall the dishes, when boiled, taste alike, or nearly so.

My invention consists in dividing one vessel, by horizontal or otherpartitions, into two or more compartments, each of which is accessibleby means of a door. Through a suitable pipe, steam is conducted into allthe compartments, and fills the same, so as to quicklyand thoroughlyboil their contents, while the surplus steam escapes, not back into theboiler, but into the fire, or, at least, off the vessel, so as not tobecome mixed up with the con-tents of various compartments. Theinvention also consists in a novel arrangement for closing the doors ofthe compartments without burning the fingers, and in a new device forindicating the want of water in the boiler, and a means of supply.

A, in the drawings, represents a rectangular or other sheet-metalvessel, of suitable dimensions, open at one side, and divided, by one ormore partitions, B B, into two or more compartments.

This vessel A is set or fixed upon a boiler, C, which may, if desired,form part of the whole appparatus. The water is poured into the boiler Othrough a pipe, D, which is arranged on the outside. of the apparatus,as shown, and which communicates with the boiler 0 through a small hole,a, near the bottom of the same. The water, standing in the pipe as highas in the boiler, will remain cool, even if that in the boiler issteaming. Only if the water in the boiler is below the upper part of thehole a will steam escape through the pipe D, and its rise will therebyindicate that water is needed in the boiler.

F is a line, which extends from the boiler (l up through eachcompartment of the vessel A, and is formed by a false wall, 6, as shown.The flue is perforated, as shown, so as to discharge the steam from theboiler into each one of the compartments of the vessel A. From theuppermost compartment, 0, of the vessel extends a pipe, G, through theflue F, and, through the boiler G, into the fire, the upper end of thepipe G being open, so that it will discharge all surplus steam into thefire.

Into each compartment can be fitted a vessel, H, with corrugated bottom,as shown. The articles to be cooked are placed into these vessels H, andthen the compartments are closed by shutting the close-fitting doors II. These doors are hinged to the box A, one or more to each compartment,and close against rubber or other packing-strips, cl, as shown. Theswinging ends of the doors carry books, on, which catch over flanges,f,on the box, as in fig. 3.

When the vessel is thus firmly closed, all the contents will bethoroughly stcamed,'and, consequently, boiled. The products ofcondensation, running down the sides in each compartment, will been thebottom thereof, under the corrugated bottoms of the vessels H, and willthereby not be' in the way of the articles to be boiled.

On the outer part of each hook or set of hooks e, of each door I,isarranged an upright wooden handle, 9,

and another upright wooden handle, it, is attached to the box A, asshown in fig. 3. -On the edge of each door is also a wooden uprightstrip, 2', as shown. These three wooden strips, g, 'h, andz', form onecomplete set of handles, for conveniently opening and closing the doorswithout coming in contact with the heated metal box or door. I

It will be seen that this apparatus, when made as described, isconveniently handled. In those now in use,

it is a source of great discomfort that the vessels cannot well be takenapart while the boiling is going on, as

they are too hot. 7 By providing the doors and the wooden handles, anyone article can be inspected without the least'inconvenience or trouble,and without disturbing the cooking-processes going on in the othercompartments.

Having thus described my invention, what I claim as new,- Jandd esire tosecure by Letters Patent,is-

1. The apparatus for cooking by steam, when made. to be one complete andinseparable vessel, having distinct compartments, for the reception ofpans or dishes, each compartment provided with a door, and so arrangedthat they are all supplied with steam from a commonboiler, by means of aside fine, having one of its Walls perforated, as herein shown anddescribed. I

2.- The vessel A, when divided, by means of partitions B, intocompartments, which are connected, by means of the flue F, with aboiler,'C, each compartment provided with steamtight doors I, and theflue F and boiler admitting of the passage-pipe G, arranged asdescribed, for the purpose specified.
